132kV Transmission Line Equipment Package
A coordinated 132kV transmission line package covering towers, conductors, insulator strings, line fittings, OPGW, earthing and project delivery control.
What is included in a 132kV transmission line material supply package?
A 132kV material package typically covers lattice towers or monopoles, ACSR/ACAR conductors, earth wire and OPGW, 145kV insulation strings, suspension and tension hardware, yoke and grading hardware, joints, repair sleeves, dampers, tower earthing, terminal interfaces, fiber fittings, inspection evidence and tower-coded packing.
TYPICAL SYSTEM BASIS

145kV strings & line hardware
Mechanical and electrical assemblies matched to the approved design.
- Composite, glass or porcelain insulator strings
- Suspension and tension hardware sets
- Yoke plates, shackles, clevises and sockets
- Grading and corona-control hardware
- Joints, repair sleeves and vibration dampers
Interface & project delivery
Terminal materials, communication and supply records.
- 145kV arresters or disconnectors where specified
- Cable sealing ends and tower earthing
- OPGW fittings, dampers and joint closures
- Prototype/type-test support as required
- Inspection records and tower-coded packing
TYPICAL APPLICATIONS

TECHNICAL COORDINATION
Interfaces to close before final quotation.
Use approved string drawings to close insulator coupling, hardware orientation and corona-control interfaces.
Coordinate conductor diameter, RTS and operating temperature with clamps, joints, repair systems and dampers.
Confirm OPGW tower attachments, down-leads and joint closure locations along the route.
Separate tower steelwork, line hardware and terminal equipment responsibilities in the BOQ.

BUYER QUESTIONS
Direct answers for 132kV procurement.
Can complete insulator strings be supplied as kits?
Yes. The approved assembly drawing should define every insulator, fitting, yoke, grading component and attachment interface.
Can tower steelwork and hardware be supplied together?
Yes when tower drawings, steel grades, bolt requirements, galvanizing specification, quantities and packing codes are confirmed.
Can KOVYEL support inspection and documents?
Yes. Required drawings, test reports, inspection points, traceability and packing records should be specified before production.
